The following detailed description of a preferred embodiment and drawings include the objects of the present invention, the solution to the problem, and the beneficial effects of the invention. Still further objects and advantages of the present invention will become apparent from the following detailed description of preferred embodiments, taken in conjunction with the accompanying drawings.

An automatic grinding machine according to the present invention, shown in FIG. 1, comprises grinding parts (100) that each provide a grinding wheel (120) on which a rotary shaft (110) is positioned perpendicular to the ground; a flat lathe part (200) placed parallel to the ground underneath the aforementioned grinding parts (100); mounting parts (300) located on the top surface of the aforementioned lathe (200) so that workpieces (A) can be mounted; jigs (400) located on both sides of each of the aforementioned mounting parts (300) so that the aforementioned workpieces (A) can be secured; and a control part (not shown) that causes a desired surface of any one of the aforementioned workpieces (A) to come into contact with one of the aforementioned grinding parts (100) by moving the aforementioned the lathe (200) in the pre-set direction axis direction.

First, the aforementioned grinding parts (100) provide grinding wheels (120) on which rotary shafts (110) are positioned perpendicular to the ground.

The aforementioned grinding parts (100) are constructed to rotate by the rotary shafts (110) positioned perpendicular to the ground, and such rotation is operated by the motor (not shown).

Each of the aforementioned grinding wheels (120) are built on one area of each of the aforementioned rotary shafts (110) that rotate.

The aforementioned grinding wheels (120) can be constructed in any shape using any material that enable grinding of metals.

More specifically, the aforementioned grinding wheels (120), shown in FIGS. 2A and 2B, are shaped like a disc with a thickness, and each should have a coating part (121) on which a diamond coating is applied along the circumferential edge.

This configuration serves to increase coating efficiency by applying the aforementioned diamond coating only to the coating part (121) in which a coating area for each of the aforementioned grinding wheels (120) is formed, while minimizing coating on other areas unnecessary for grinding and increasing cost efficiency.

Next, the aforementioned lathe part (200) has a flat surface and is placed parallel to the ground underneath the aforementioned grinding parts (100).

More specifically, the aforementioned lathe (200) comprises a lathe top (210) and a lathe bottom (220), and the aforementioned lathe bottom (220) includes a flat body having an inner space while the aforementioned lathe top (210) is located on top of the aforementioned lathe bottom (220) and designed to allow sliding.

For the aforementioned lathe top (210) to slide, it consists of X-axis sliding parts (230), a Y-axis sliding part (240), and Z-axis sliding parts (250).

The aforementioned X-axis sliding parts (230), Y-axis sliding part (240), and Z-axis sliding parts (250) are built so that the pre-set position of the aforementioned lathe top (210) can be shifted by a pre-set value as it is controlled by the control part (not shown) described below. This configuration serves to allow any one of the aforementioned workpieces (A) to be mounted on top of the lathe (200) and then a desired surface of the workpiece (A) to be effectively positioned on one of the grinding parts (100).

First, the aforementioned X-axis sliding parts (230), shown in FIG. 3, each consist of primary (231) and secondary (232) rails, and the aforementioned secondary rail (232) allows the aforementioned lathe (200) to slide on the aforementioned primary rails (231) in a certain direction (X-axis) parallel to the ground.

More specifically, each of the aforementioned X-axis sliding parts (230) is made up of the primary rails (231) on both sides inside of the lathe bottom (220), on which the part slides, and the secondary rail (232) which is a rail in and of itself.

Next, the aforementioned Y-axis sliding part (240) is included to allow the aforementioned lathe (200) to slide in the direction (Y-axis) perpendicular to the X-axis on which each X-axis sliding part (230) slides parallel to the ground.

More specifically, the aforementioned Y-axis sliding part (240) is built so that it can move along the aforementioned secondary rail (232) on top of the secondary rail (232).

The aforementioned lathe top (210) is connected to the aforementioned Y-axis sliding part (240) and rotates.

Next, the aforementioned Z-axis sliding parts (250) are built to allow the aforementioned lathe (200) to slide in a direction perpendicular to the ground.

More specifically, the aforementioned Z-axis sliding parts (250), shown in FIG. 1, are each formed on the legs that support the lathe bottom (220) and are adjustable to a desired height from the ground.

Next, the aforementioned mounting parts (300) are formed on the top surface of the aforementioned lathe (200) allowing workpieces (A) to be mounted.

The aforementioned mounting parts (300) are shaped like a disc and should be constructed to allow the aforementioned workpieces (A) to be precisely mounted in pre-set locations.

To that end, the aforementioned mounting parts (300), shown in FIG. 4, further include fixed projections (310) and fixed projection rails (320).

Multiple fixed projections (310) are provided in radial form on the top surface of each of the aforementioned mounting parts (300).

Fixed projection rails (320) are built on top of each of the aforementioned mounting parts (300) so that the aforementioned fixed projections (310) can rotate about the central axis of the aforementioned mounting part (300) or in the opposite direction.

Each of the aforementioned fixed projections (310) can rotate on each fixed projection rail (320) in the direction of the central axis of the aforementioned mounting part (300) or in the opposite direction of the central axis of the aforementioned mounting part (300). Several of the aforementioned fixed projections (310) can move at identical intervals in the same direction to secure the aforementioned workpieces (A).

The center of each workpiece (A) can be positioned by each fixed projection (310) and each fixed projection rail (320) on top of the mounting part (300) on the same line as the center of the mounting part (300).

More springs can be added to the aforementioned fixed projections (310).

After the aforementioned fixed projections (310) are moved by the aforementioned springs and the force is removed, they can be adjusted to return to their original position.

Next, the aforementioned jigs (400) are each built on both sides of each of the mounting parts (300) to secure each workpiece (A).

More specifically, the aforementioned jigs (400), shown in FIG. 5, each consist of a jig base (410), holding portions (420), and a rotating part (430).

First, the aforementioned jig base (410) has a body fitted in between the aforementioned mounting parts (300).

Next, the aforementioned holding portions (420) extend from both ends of the aforementioned jig base (410) and are built to secure the aforementioned workpiece (A).

The aforementioned holding portions (420) can be built in any shape as long as they are able to secure workpieces (A).

Furthermore, the aforementioned holding portions (420) are detachable and should be able to be replaced at the operator's option.

Next, the aforementioned rotating part (430) is coupled to the aforementioned jig base (410) at the bottom allowing the aforementioned jig base (410) to rotate.

Until a workpiece (A) is mounted on a mounting part (300) by the control of the control part (not shown), as shown in FIG. 6, the rotating part (430) is in standby mode so that the holding portions are facing in the direction of the X-axis. After the aforementioned workpiece (A) has been mounted, the rotating part (430) begins to rotate again in the direction of the Y-axis so that the holding portions (420) can secure the aforementioned workpiece (A).

Next, the aforementioned control part (not shown) is controlled to move the aforementioned lathe (200) in the pre-set axis direction so that a desired surface of the aforementioned workpiece (A) comes into contact with one of the grinding parts (100).

More specifically, upon being assigned inputs for the X-axis, Y-axis, and Z-axis from the pre-set program, the aforementioned control part (not shown) moves the aforementioned X-axis sliding parts (230), Y-axis sliding part (240), and Z-axis sliding parts (250).

Furthermore, as the X-axis sliding parts (230), Y-axis sliding part (240), and Z-axis sliding parts (250) move, the aforementioned rotating part (430) begins to rotate, causing the aforementioned holding portions (420) to rotate towards the workpiece (A) and secure it.

The following describes the mechanism of the invention comprising the aforementioned parts.

First, a workpiece (A) is mounted on each mounting part (300).

To mount the aforementioned workpiece (A), each fixed projection (310) should be rotated so that the workpiece (A) can be mounted on top of the mounting part (300). After the workpiece is mounted on top of the mounting part (300), the aforementioned fixed projection (310) is rotated to position the workpiece (A) in the center of the mounting part (300).

Next, by operating the aforementioned control part (not shown), a desired surface of the workpiece (A) is caused to come into contact with the surface of the grinding part (100).

Then, according to the settings of the aforementioned control part (not shown), the lathe (200) rotates, causing the desired surface of the workpiece (A) to come into contact with the surface of the grinding part (100).

The aforementioned control part (not shown) should be programmed to move the contact area between the workpiece (A) surface and the grinding part (100) after the two surfaces come into contact, allowing all desired surfaces to be ground.

The aforementioned lathe (200) is rotated by the sliding motion of the X-axis (230), Y-axis (240), and Z-axis sliding parts (250).

The aforementioned jig base (410) is rotated by the rotating motion of the rotating part (420) at the same time as the rotation of the lathe (200), which causes the workpiece (A) to come into contact with the holding portions (420) of the jig (400) and be secured.

The machine is programmed so that, once a grinding operation is finished, the lathe (200) and the jigs (400) return to their original positions.
